No apologies needed, by turning off each breaker and logging what is turned off by each you may be able to figure out which breaker is the one that feeds these outlets and hopefully you will find some light or outlet somewhere that is on the same line. If not leave it turned off as you may have a broken wire in a wall. Good luck.

Bingo! Thanks to all for the assistance. I just got home from work and looked behind the junk piled up against the garage wall. Sure enough, there is a GFCI that was tripped. I reset it and all is fine.

Victor. That's great news to save this problem next time, add a gfi to the first outlet outside and on the one in the garage with pigtails hook both sets of wires to the line side. That way if the outside one kicks it can be set from outside and won't bother the inside one.

Vector,
So there's no power at the outlet right below the breaker box outside the house? Can you get access through an attic above the garage to see which wire set is running down to the outlet? Why are you testing all the breakers, did they not label which breaker powers that outlet? Do you see little green men running out of the breaker box? I've heard those leprechauns can be pretty awful, though not as bad as the gremlins.

Alternatively, I've seen where people have driven a nail through a power cable and caused it to trip and then it went bad so it never came back on again. Check the breaker that powers those outlets and switch the wire to another breaker and see if it works then? Is there a sub panel somewhere that could be powering the outdoor sockets (crazy but I've seen worse).
